Application filed November 30, 1894. Serial No. 530,338. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES A. TATUM, a, resident of the city, county,-and State of New York, have invented certain new and useful Improvements in Suppository-Machines, of which the following is a specification.

My invention relates to machinesfor making suppositories, and has for its object to produce 'a reliable machine which will operate efficiently to produce a molded suppository. 7

To this end my invention consists in the construction hereinafter set forth and claimed.

My invention will be understood by reference to the accompanying drawings, where- 1n- Figure 1 is an isometric view of a complete machine embodying my invention. Fig. 2 is a similar view with the mold cylinder removed. Fig. 3 is a detached isometric view of the mold cylinder. Fig. 4. is a longitudinal section thereof on line t4. of Fig. 3. Fig. 5 is a detached view of the mold gate for the mold cylinder; and Fig. 6 is an isometric View of a receiving tray for the complete suppository.

In the drawings, A is the bed-plate of the machine and upon this bed-plate are mounted standards A A which constitute mountings for the working parts of the machine and receive the strain of the working. These standards A A are united by retaining rods B B which are held firmly in place by nuts a a. The bed-plate, standards and retaining rods constitute the frame of the machine. The retaining rods are in turn united by loops or stirrups b b for the reception of the mold cylinder and provided with lugs c c for preventing lateral motion of the mold cylinder when the mold is in the cylinder and receiving the thrust of the mold cylinder when during the operation of the machine the mold cylinder comes against them. One of these lugs may be dispensed with if desired.

O is the mold cylinder in which is screwed or otherwise mounted a removable suppository'mold D of suitable construction. This mold cylinder rests on' suitable supports, shown in the present instance as loops or stirrups b andis provided with lugs d, which engage with the retaining rods B B to prevent the mold cylinder from turning. The mold cylinder may also be provided with a lifting ring 6 for lifting the same.

E is a screw rod which is threaded in the standard A and works therein, and is provided with a wheel F or other means of turning the same, and extends within the frame of the machine and terminates in a plunger G which works in the bore of the mold cylinder. (See Fig.1.)

H is a movable mold gate which is provided with wings h and is placed in the machine between the mouth of the suppository mold and the standard A and rests against such standard, which forms an abutment for the mold gate. rest upon the retaining rods which serve to support it.

I is a receiving tray which is secured to the standard A by screws passingthrough ears 'i formed integral with the tray. This tray serves to receive the suppositories when molded.

The operation of my device is as follows: The mold cylinder is first filled with the desired substance for forming the suppositories, such for instance, as cacao butter and the mold cylinder and mold placed in the retaining frame in the position shown in Fig. 1. The plunger is now entered into the mold cylinder and shoved forward therein by turning the wheel F, thereby screwing the screw rod E into the standard A It will of course be understood that the mold gate H is in place. As the plunger continues to move for- The wings of the mold gate ward in the cylinder, the cacao butter is comis' withdrawn from themold cylinder and the mold cylinder and mold lifted out when the of the cylinder, and a plunger mounted in mold cylinder may be refilled. some fixed part of the machine and working What I claim, and desire to secure by Letin the cylinder and serving to retain the cylters Patent, isinder in place in the machine when the plunx5 5 In a suppository machine, the combination ger is entered into the cylinder, substantially of suitable snpports,t'orining part of aretainas described. ing frame for the cylinder; a cylinder resting loosely in the supports, lugs upon the retain- CHARLES TATUM' ing frame for receiving the longitudinal Witnesses: 1o thrust of the cylinder, a mold gate, a mold co- HARRY M.
